PRODUCT OVERVIEW
Rarely, has a Series of low-power DC/DC converters
been defined by both low cost and Murata’s quality
and reliability. Our new BST Series of dual-output
3W DC/DC’s achieves this “best-of-both-worlds”
status by implementing a proven circuit architecture
(170-200kHz flyback design) as a full, SMT-on-pcb
assembly (including surface-mount magnetics) that is
truly 100% automatically assembled. Packaged in min-
iature 1.25" x 0.8", DIP-like plastic packages (UL94V-0
rated) and requiring no external components, BST
Series DC/DC’s bring true component-like convenience
to designers of today’s distributed power systems.
Output voltages are ±5, ±12 or ±15 Volts. Input
voltage ranges are 4.5-9V (“D5” models), 9-18V
(“D12” models) or an ultra-wide 18-72V (“D48”
models). BST DC/DC’s are fully isolated (1000Vdc
guaranteed) and include input (pi type) and output
filters within their package. Output transient response
is a quick 200μsec, while output ripple and noise are
typically 75mVp-p.
These rugged modules are fully encapsulated
with a thermally conductive potting compound that
contributes to their outstanding moisture/vibration
resistance and impressive MTBF. They operate over
the full –40 to +75°C temperature range without der-
ating. All models have been thoroughly characterized
(electrically, mechanically and thermally), qualified
(including HALT), and EMI/EMC tested. Additionally,
they are certified to UL1950, CSA 22.2 No. 950 and
IEC950.
Murata’s BST Model 3W DC/DC’s are excellent
selections for telecom/datacom, computer and
process-control applications demanding small size,
low cost and high reliability. If required, their design
“flexibility” allows for easy modification to your
application-specific requirements.
